Features

• Heavy-Wall Borosilicate Glass Construction Crafted from premium 3.3 borosilicate glass with thick walls (3.5-5mm) for superior thermal and mechanical strength. Withstands direct flame heating, vacuum conditions, and extreme temperature changes without cracking.
• Standard 24/40 Taper Joint – Outer Joint Precision-ground 24/40 outer joint ensures airtight, leak-proof connections with condensers and adapters. Interchangeable with other standard lab glassware for seamless integration in organic chemistry setups.
• Round Bottom for Uniform Heat Distribution Round bottom design promotes even heating, reduces hotspots, and minimizes stress fractures. Requires support via cork ring or clamp – recommended for controlled heating with mantles or water baths.
• Hand-Blown Quality – Stress Relieved & Impurity-Free Each flask is handcrafted and annealed at high temperatures for optimal clarity and structural integrity. No bubbles or contaminants–ensuring reproducibility in critical lab procedures.
